The Cane Toad was introduced into Australia in 1935 as a means to control sugarcane-eating beetles. This failed because the beetles fed and lived higher than the toads could reach. The toad population then grew out of control; laying up to 30,000 eggs at a time, compared to 2,000 from most native frogs. Due to their poisonous nature, they have no predators, allowing them to spread across the continent with little resistance.
